Dealing with hot spots or wasted light in your grow room? Flashgro On White 4' x 50' Reflective Film is the professional solution for growers looking to maximize their light efficiency. This high-performance film ensures that every lumen from your grow lights is directed toward your plants, promoting healthier growth and higher yields by eliminating dark corners and maximizing coverage.
Constructed with a premium metalized polyester surface and a rugged woven poly backing, this film is designed for longevity and versatility. Unlike standard, thin mylar films, Flashgro's tough construction allows it to be stapled, nailed, or glued to any surface without the risk of easy tearing. For smaller areas, you might prefer the Flashgro On White 4' x 25' Reflective Film, while the Flashgro On White 4' x 100' Reflective Film is ideal for large-scale operations.
As a core component of the Flashgro collection, this reflective film is engineered to handle the high-humidity environments of indoor gardens. It reflects both heat and light in a perfectly even, dispersed pattern, which is critical for preventing thermal hot spots that can stress or burn your canopy. It is an essential upgrade for any serious indoor setup.
Metalized polyester surface ensures maximum light return to your plants.
Woven poly backing provides superior strength and tear resistance.
Can be easily stapled, nailed, or glued to any grow room surface.
Reusable and incredibly easy to clean for multiple grow cycles.

The Flashgro On White Reflective Film is covered by a standard manufacturer's warranty against defects in materials and workmanship. Please ensure proper handling during installation to maintain the integrity of the reflective surface.
You can easily clean the film using a soft cloth with mild soap and warm water. Avoid abrasive cleaners that could scratch the metalized surface.
While extremely reflective, this film is designed primarily to bounce light back into the canopy. If you require 100% light-blocking capabilities, we recommend layering it or using dedicated blackout materials.
Yes, Flashgro is designed to reflect both light and heat from all types of grow lights, including LED, HPS, and MH systems.
The woven poly backing is very strong, so you can securely use staples, small nails, or heavy-duty spray adhesive to mount it to your grow room walls.
The woven backing makes it much more resistant to permanent creasing and tearing compared to standard thin mylar, making it easier to handle and install smoothly.
